Perforated metal sheets: What you need to know

Metal sheets have a wide-ranging use in manufacturing where they often form the starting point for everything from boxes to tables, chairs and even car parts. What many manufacturers don't realise is that it's not just standard metal sheets that can be used for these purposes. There are also a great many applications for perforated metal sheets. Perforated metal sheets can be used for everything from industrial applications and computer fan cases to cooking utensils and architectural cladding features. While many metals can be employed in these ways, the two most commonly used metals from which perforated metal sheets are made are mild steel and aluminium since they are both durable and extremely versatile.

How are perforated metal sheets made?

Perforated metal sheets start life as conventional metal sheets before the perforations are applied. Clearly, with so many perforations in each sheet, it isn't economical to have each hole created individually. Instead, the sheet is fed through a machine, which uses a hole punch to create all of the perforations. Using this method, an entire row or even multiple rows of perforations can be created at one time.

The size and shape of the perforations needed can vary, depending on the purpose to which the sheet will be put. It's possible that a fine mesh could be required if the sheet is to be applied to engineering purposes, perhaps as a filtration device. Alternatively, a more decorative pattern could be used if the sheet is destined to become architectural cladding or an item of street furniture.

How can you work with perforated metal sheets?

Sometimes, perforated metal sheets can be supplied to the customer ready for them to take to the next stage. On other occasions, you could ask the manufacturer to prepare them for you in some way. You might get them to cut the sheet to size for you or maybe coil it or bend it to shape to make storage or processing easier for you. In addition to that, you could ask for the sheet to be cleaned or painted in advance of delivery to reduce the amount of work that you need to carry out on the material.

Why not talk to your supplier today to find out how you could incorporate perforated metal sheets into your next product? They will be able to advise you on what types and sizes of perforations are possible and how you might be able to use them.
